DeWalt DCMST911 Instructions D’origine page 31

Maintain a minimum distance of 610 mm (24") between the
guard 12 and your feet as shown in Fig. L.

WARNING: Keep the rotating string roughly parallel with the
ground (tilted no more than 30°). This trimmer is not an edger.
DO NOT TILT the trimmer so that the string is spinning near a
right angle to the ground. Flying debris can cause serious injury as
shown in Fig. K.
Bump Feed Trimmer Line Feed (Fig. N, O)
Your trimmer comes with 2.4 mm (0.095") but can also use 2.0 mm
(0.080") diameter nylon line. Cutting line
require more feeding if the cutting is done along sidewalks or other
abrasive surfaces or heavier weeds are being cut.
As you use the trimmer, the string will get shorter due to wear.
Gently bump the trimmer on the ground while running at
normal speed and the cutting line
nOTE: Extending the cutting line
blade 32 will negatively effect performance, runtime, and the
life of the trimmer due to potential of damaging motor. Doing
so may void the warranty.
Helpful Trimming Tips
• Use the tip of the string to do the cutting; do not force string
head into uncut grass.
• Wire and picket fences cause extra string wear, even breakage.
Stone and brick walls, curbs, and wood may wear string rapidly.
• Do not allow spool cap to drag on ground or other surfaces.
• In long growth, cut from the top down and do not exceed
300 mm (12") high.
• Keep trimmer tilted toward the area being cut; this is the best
cutting area.
• The trimmer spins counterclockwise when viewed from
behind and above. Cutting from right to left will throw debris
toward the guard and catch the trimmings. It is recommended
to cut from right to left when near gardens or flower beds as this
will help to keep trimmings from being thrown into those areas.
Cutting from left to right will throw debris away from the guard.
Use this method when debris location is not important.
• Avoid trees and shrubs. Tree bark, wood moldings, siding, and
fence posts can easily be damaged by the string.
